Broken Platform regulator pin

[Lenj]

Hi All,

I have a platform escapement with a broken regulator pin, can you buy these pins or do they have to be made specially, or can you make them yourself. if so How??

Any help as always much appreciated..

 

Thx Len

That looks like new platform. So I'm guessing its one of these on this page, If I'm right you can buy a replacement part. It is a regulater index. Watch and Pocket watch pins will not be big enough. You could make one.

I would say something like this? https://www.cousinsuk.com/product/hairspring-collets-pins-wristwatch

Haven't done it myself. But would be great to see. If you do it please post. I think Practical watch repair by Donald de Carle show it in the book.

I have a selection of these pins from Cousins. If you let me know the major diameter and the length I can tell you if anything there will fit

Hi All, 

Thanks for getting back to me and thanks to Old Hippy for the link and Stuart ad Rogart63 for the info..I was not expecting to have to buy a unit to fit, just fit a new pin, and yes is a modern one, but that is a great idea if I can't get a pin.

The pin hols size is 0.01mm if they are made??

Thx again Len

Sorry hole size 0.5mm ….pin length 1.5 approx

 

Thx len

Really? 0.01mm? Maybe inches??

I just grabbed a largish  looking one out of the packet. The head diameter was 0.6mm and the pin length (minus the head) was 2.3mm.

The packet really does have quite an assortment with different head and pin lengths and diameters.

I would send you one if you knew exactly what you needed, but some of the heads are tapered and some straight, so if this sounds about right then you might find it best to get the assortment to choose the best fit

Ah, cross post! You re-measured! Sounds more like it

Hi Stuart,

Yes I re-measured and yes your size sound great, I measured the hole size with a drill that was 0.5mm, the length was with a ruler, so not that accurate..

Thx Len
